Restoring Tropical Biomes for Climate Mitigation
Publicado em 16 março 2023
Brazil must maintain and restore its dry forests and savannas to meet its climate goals, says recent research.
Attention is frequently focused on the Amazon rainforest, neglecting the harm and loss of these seasonally dry biomes, which possess tremendous biodiversity and carbon stores, both in Brazil and across the world.
According to the latest study, spearheaded by the universities of Exeter and Campinas, cost-effective restoration of savannas and dry forests might lock in 1.5 billion [...]

Deforestation Results in Increased Active Fires in the Brazilian Amazon
Publicado em 15 fevereiro 2023According to recent research published in the journal Nature Ecology & Evolution, the number of active fires documented in the Brazilian Amazon in August – September 2022 was the greatest since 2010. Aside from the record number of fires (74,398), the scientists discovered they were caused by recent human deforestation rather than extreme drought, as in 2010. A Brazilian study identified more than 74,000 active fires in the period. They were not mainly due to extreme drought, the [...]ver notícia -
Biogas Produced from Apple Pomace Could Help Reduce Fossil Fuel Consumption
Publicado em 10 fevereiro 2023Scientists at the State University of Campinas (UNICAMP) and the Federal University of the ABC (UFABC) in São Paulo state, Brazil, have successfully produced biogas from apple pomace, the pulpy residue remaining after the fruit has been crushed to extract its juice. An article describing the research is published in the journal Biomass Conversion and Biorefinery. The key concept is that of the circular economy, a system of closed loops designed to reduce costs, recover [...]ver notícia -
Effects of High Intensity Heatwaves on Estuarine Habitats
Publicado em 19 janeiro 2023According to recent research published in Estuarine, Coastal and Shelf Science by researchers working in Brazil, Norway, and the United States, an increase in marine heatwaves as a result of global climate change in the coming years will have a noticeable impact on lifeforms in the environment, including those at the bottom of the food chain. Marine heatwaves are described as periods of more than five days with water temperatures more than 90% higher than the region’s historical [...]ver notícia -
Effects of Climate Change on Rainforest’s Carbon Storage
Publicado em 14 setembro 2022The innumerable advantages of native forests include the ability of tree biomass to capture large volumes of carbon, which can offset greenhouse gas emissions into the air. An article published in the journal Science Advances describes a novel examination of a large dataset intended to elucidate the theory of carbon sequestration, a strategic subject in the dialogue concerning global climate change. “We still know little about the factors that can lead forests to store more or less [...]ver notícia -
Novel Strategy Converts Methane into Liquid Fuel Using a Photocatalyst
Publicado em 03 agosto 2022Scientists have successfully converted methane into methanol using light and dispersed transition metals like copper through a process called photo-oxidation. The reaction was the greatest one yet for converting methane gas into liquid fuel under ambient settings of temperature and pressure (25 °C and 1 bar, respectively). The study was published in the journal Chemical Communications. The Greek word for weight (baros) is where the word “bar” as a unit of pressure [...]ver notícia -
Deforestation of Indigenous Lands Endangers Brazil’s Ability to Meet Climate Change Mitigation Targets
Publicado em 20 abril 2022Indigenous lands in the Brazilian Amazon are under constant pressure, and deforestation of these areas has accelerated in recent years. Some of them, such as Apyterewa Indigenous Territory in Pará state, are particularly affected, endangering Brazil's ability to meet the targets to which it is committed internationally in terms of combating deforestation and mitigating the impact of climate change. To protect the areas of the Amazon that are still intact, effective action must be [...]ver notícia -
Deforestation and Climate Change Worsen the Severe Drought Conditions in Brazil
Publicado em 07 março 2022Deforestation for agribusiness expansion in Brazil, in conjunction with climate change, has worsened the already severe drought suffered in the last decade by the transition zone between the eastern Amazon and the Cerrado, the vast tropical savanna ecoregion in central and western Brazil. This combination of trends endangers the stability of the biomes concerned and constitutes a risk to food production in the region known as MaToPiBa, a portmanteau of Maranhão, Tocantins, [...]ver notícia -
Fiscal Transfer Mechanism Increases the Nature Reserves in Atlantic Rainforest Areas, but with Partial Results
Publicado em 06 dezembro 2021A study by the University of São Paulo (USP) in Brazil investigated a fiscal transfer mechanism whereby states transfer part of their sales tax revenue to municipalities in exchange for the creation of environmental conservation units. The mechanism is known as ICMS-E. ICMS is state-collected sales tax, and the "E" stands for ecological. In an article published in the journal Ecological Economics, the researchers show that although the fiscal transfer mechanism has stimulated [...]ver notícia -
Study Reveals Forest Fires Affect Rain Cloud Formation in the Amazon
Publicado em 28 outubro 2021Brazilian researchers illustrate how wildfires and forest burning for agriculture purposes impacts rain cloud formation in the Amazon. Details of the research have been published in the journal Communications Earth & Environment. Particles released into the atmosphere by fire modify the water droplet freezing process and can affect precipitation, according to a paper in Communications Earth & Environment.
